This gospel tract really gets to the heart of the matter, that what really matters is eternity.

Point to the tract and ask the person, "What will matter to you in 150 years time?" They'll probably say, "I'll be dead." You can reply, "Exactly. The only thing that will matter to you then is where you will be, whether in Heaven or in Hell. So what you are worried about now, and spend all your time on now, will not matter in the long run. The only thing that matters in the long run is whether you go to Heaven or Hell." Then you're into a witnessing encounter.

This tract is business card size so it fits easily in people's pockets and is only $5 for a pack of 100.
